We found the 2007 GMC Acadia comfortable after a couple hundred miles behind its tilt and telescoping wheel. In addition to plenty of head room, there's a sliding padded center armrest provided for an optimum fit, slightly rubberized door sills for resting forearms, and padded door armrests serve as a cozy respite for the occasional elbow. The front buckets feature long lower sections for thigh support, and the cushions are a suitable compromise between firm and cushy. However, the front lower side bolsters proved insufficient in even gentle corners, though those on the back rest worked well enough to keep torsos in place.
